Making LED displays and signage is a complete industry in itself serving all sorts of clients like banks, railway stations, factories, airport and more. In earlier days display units were made using individual LEDs carefully placed and soldered to make matrix of display. But this task was very mundane and slight misplacement of LED gave […]

Story Introduction This is my first Arduino project. My work was inspired by several maker projects that created Persistence of Vision Displays [2,3,4]. Persistence of vision (POV) refers to the optical illusion whereby multiple discrete images blend into a single image in the human mind and believed to be the explanation for motion perception in cinema and animated films [1]. The

Story More VideoBlasting So why didn’t the TVout library reach any higher resolution than 160×100? The answer is simple. They did not use any hardware onchip to push the pixels out. If you use the SPI to push the pixel you will gain an immediate 1:1 in pixelspeed The SPI push out data at the

Story SSD1306xLED is a C library for working with the SSD1306 display driver to control dot matrix OLED/PLED 128×64 displays. It is intended to be used with the Tinusaur board but should also work with any other board based on ATtiny85 or similar microcontroller. The 128×64 OLED is controlled by a SSD1306 circuit and could be

Microcontrollers are capable of detecting binary signals: is the button pressed or not? These are digital signals. When a microcontroller is powered from five volt, it understands zero volts (0V) as a binary 0 and five volts (5V) as a binary 1. But the real world is not so simple and likes to use shades
